Another great example of what forums are for. Think of how much money you saved not taking it to a stealership or local shop!
My friend I just joined the forum to thank you for that little piece of advice. The MAF trace looked reasonable on my scanner so I spent a lot of time looking for vacuum leaks and cleaning injectors. Pulled the MAF sensor cable and idled fine. Replaced the sensor and all is well. Fixed my lousy idle and maxed out fuel trim. Thanks much.Have you tried pulling the plug on your maf to let it run on substituted values to see what happens to your stft?
